"The idea of War was to possibly use different producers for each song or group of songs so the approach would vary throughout but in the end it didn't happen and we sorted it out with Steve Lillywhite. We understand each other and it works well for us. He has helped us grow and mature to understand recording techniques and translate our sound and ideas into reality." - Bono on War, 1983
